hi, this is looking quite cool. It'll be quite a challenge to animate and choreograph a fight. Just out of curiosity, have you animated anything that complex before?
For your lightsaber glow, why not do it in post. After effects, shake etc.
That will give you a lot more control and if you want change you won't have to re-render.
There is a very good glow plugin, you can download a three week trial version for almost any composing app. and it works just like the full version when you render, no water marks or anything like that.
